Product Description:

The HCS02.1E-W0070-A-03-NNNN belongs to the HCS IndraDrive Controllers series produced by Bosch Rexroth Indramat. It is an AC drive controller intended to regulate power to servo or induction motors within automated machinery. By monitoring motor feedback and modulating output, the unit coordinates motion sequences and maintains torque accuracy in conveyor, packaging, and handling equipment used across manufacturing cells. This control behavior helps the connected motor respond smoothly to speed changes, load variation, and repeated start-stop cycles that are common in automated production equipment.

This controller has an IP20 enclosure rating, so it provides basic finger-safe shielding and is intended for cabinet installation. It accepts a 3 × AC 200 to 500 V ±10% three-phase supply, allowing operation on a wide range of industrial mains. That input range supports use in facilities with different standard line voltages without requiring tap changes. During rapid acceleration, the inverter section can deliver a device peak current of 70 A. The power electronics support a continuous output range of 1.5 to 11 kW, which allows the same controller platform to serve different axis sizes. The communication interface is not specified in the available information, so the fieldbus option must be confirmed for the intended system.

Thermal management relies on internal air cooling provided by a built-in blower, so no external ducting is required. The unit uses design version 1 within the series. DC link energy is exchanged through an infeeding/feeding power supply topology, which supports shared bus arrangements where braking energy from one axis can be used by another axis. The controller is categorized under HCS02 within the product line. This layout is suitable for multi-axis systems that exchange energy across a common DC bus. Its parameter structure remains consistent with other IndraDrive components used in the same installation.

Fault / Error What it Means Corrective Action
Drive will not power up (no LEDs) Control- or mains-power absent / undervoltage Verify 3-phase mains input and stable 24 V control supply at X31; inspect fuses and wiring
F8025 – Overvoltage in power section DC-bus voltage exceeded safe limit Lengthen deceleration ramps, check / size braking resistor, confirm mains voltage
F8028 – Overcurrent in power section Short-circuit or excessive motor current Inspect motor- and brake-cables for shorts, test insulation, review current-loop parameters
F8064 – Interruption of motor phase One motor phase open-circuit Continuity-test each phase, reseat connectors, repair or replace cable / motor
F8022 – Encoder 1 signals incorrect Feedback not recognised or noisy Reseat encoder cable, verify shielding / grounding, match feedback type in parameters
F8070 – +24 V DC error Auxiliary control supply lost or low Measure 24 V rail, check PSU capacity and terminations, restore stable supply
F8057 – Device overload shutdown Inverter heat-sink temperature or load exceeded Check fan airflow, clean filters, keep ambient ≤ 45 °C, reduce continuous load
F4009 – Bus failure Fieldbus communication with PLC lost Check network cabling & termination, verify master status, reset drive after bus recovers
F6028 – Position limit value exceeded Axis moved outside software travel limits Clear fault, jog axis back within limits, correct position-limit parameters
F8120 – Invalid control-/firmware combo Mismatch between firmware and hardware Flash the correct firmware or install a matching control section
